  • Left to Right

Algebra I

  • Reading a Cartesian Plane
  • Coordinates (x, y)
  • Slope Formula:
    \displaystyle m=(y_2-y_1)/(x_2-x_1)

Explanation:

Step 1: Define

Find points from graph.

Point (-1, 3)

Point (2, 9)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

  1. Substitute in points [Slope Formula]:
    \displaystyle m=(9-3)/(2+1)
  2. [Slope] Subtract/Add:
    \displaystyle m=(6)/(3)
  3. [Slope] Divide:
    \displaystyle m=2
